7.2.3 Zero Point Return (ZRET)
7-16
( 2 ) Signals Used for Zero Point Return
The following table shows the details on the signals used for zero point return operation.
* 1. The polarity can be inversed by setting the fixed parameter No. 20, bit 1 (C Pulse Input Signal Polar-
ity Selection).
* 2. The polarity can be inversed by setting the fixed parameter No. 1, bit 5 (Deceleration LS Inversion Selection).
16 N-OT & C pulse
Uses the negative overtravel signal and
phase-C pulse.
N-OT: DI_4 7-51
17 N-OT Only Uses only the negative overtravel signal.
N-OT: DI_4
This method must not be used if repeat
accuracy is required.
7-52
18 INPUT & C pulse
Uses the INPUT signal and phase-C
pulse.
INPUT: OW 05, bit B 7-53
19 INPUT Only Uses only the INPUT signal.
INPUT: OW 05, bit B.
This method must not be used if repeat
accuracy is required. 7-55
